La publication FR-A-2556289 décrit un dispositif répartiteur d'air dans lequel le volet de dosage de l'air recycle et le volet d'admission associent deux obturateurs séparés par une fenêtre mobile dont l'un ferme l'orifice d'entrée de l'air de recyclage. Lorsque le vehicule circule dans un environnement pollué il est important d'isoler temporairement l'habitacle de l'air extérieur en assurant une circulation dynamique de l'air recyclé sans risque d'accroissement du taux d'humidité de l'air dans l'habitacle et les inévitables dépôts de buée sur les vitres du vehicule.Publication FR-A-2556289 describes an air distributor device in which the recirculating air metering flap and the intake flap combine two shutters separated by a movable window, one of which closes the inlet opening recirculation air. When the vehicle is traveling in a polluted environment it is important to temporarily isolate the passenger compartment from the outside air by ensuring a dynamic circulation of the recycled air without risk of increasing the humidity of the air in the passenger compartment and the inevitable deposits of mist on the vehicle windows.
Conformément à l'invention le problème est résolu en ce que le volet de recyclage et le volet d'admission sont respectivement disposés dans des chambres en communication avec une volute du ventilateur dans laquelle débouche la gaine d'alimentation d'un boîtier du distributeur de l'air de chauffage et de ventilation et en ce que la commande d'ouverture dudit volet de recyclage actionne le ventilateur.In accordance with the invention, the problem is solved in that the recycling flap and the intake flap are respectively arranged in chambers in communication with a volute of the fan into which the supply duct of a distributor box opens. the heating and ventilation air and in that the opening control of said recycling flap actuates the fan.
Le dispositif ainsi réalisé permet notamment d'accélérer le réchauffage de l'air de l'habitacle en le recyclant en totalité ou partiellement au travers d'un échangeur thermique dispose dans le boîtier du distributeur de l'air de chauffage et de ventilation.The device thus produced in particular makes it possible to accelerate the heating of the air in the passenger compartment by recycling it in whole or in part through a heat exchanger placed in the housing of the distributor of the heating and ventilation air.

La combinaison des volets 31, 33 et du dispositif de commande incluant l'organe de manoeuvre 36 permet l'asservissement des positions relatives des volets 31, 33 qui assure notamment :
- l'ouverture du volet d'admission 31, lorsque le volet de
recyclage 33 est fermé conformément à la figure 3, dans le but de permettre l'aspiration d'un flux d'air extérieur maximal, - l'ouverture du volet de
recyclage 33, lorsque le volet d'admission 31 est fermé conformément à la figure 4, dans le but de permettre le recyclage complet de l'air de l'habitacle. - l'ouverture des volets d'admission 31 et de
recyclage 33 dans le but de favoriser simultanément :
l'entrée de l'air extérieur (60 % environ) sous une pression dynamique faible générée par une vitesse d'avancement modérée du vehicule,
l'entrée de l'air de l'habitacle pour recycler l'air de l'habitacle afin de permettre une montée progressive de la température de l'habitacle sans risque de dépôts de buée sur la face interne du vitrage, conformément à la figure 5. - l'ouverture des volets d'admission 31 et de

intake flap 31, when therecycling flap 33 is closed in accordance with FIG. 3, in order to allow the suction of a maximum external air flow, - the opening of the
recycling flap 33, when theintake flap 31 is closed in accordance with FIG. 4, in order to allow complete recycling of the air in the passenger compartment. - the opening of the
admission 31 and recycling 33 flaps with the aim of simultaneously promoting:
the entry of outside air (around 60%) under a low dynamic pressure generated by a moderate forward speed of the vehicle,
the air intake from the passenger compartment to recycle the air from the passenger compartment in order to allow a gradual rise in the temperature of the passenger compartment without the risk of fogging on the internal face of the glazing, in accordance with the figure 5. - the opening of the
admission 31 and recycling 33 flaps with the aim of simultaneously promoting:
the entry of outside air (approximately 60%) under a strong dynamic pressure generated by the high speed advancement of the vehicle.
